The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

FIGS. 1-3 illustrate one embodiment of a heat dissipating device. The heat dissipating device can be secured to an electronic device, such as a server computer, to dissipate heat generated from the electronic device. The heat dissipating device comprises a chassis 10 and a first heat dissipating member 20.

The chassis 10 comprises a bottom plate 11, two side plates 13, and a first support plate 17. The two side plates 13 are located on the bottom plate 11 at opposite sides. The chassis 10 defines an input opening 19 and an output opening 14 between the two side plates 13. The first support plate 17 defines a first ventilation opening 175 located between the two side plates 13 and between the input opening 19 and the output opening 14.

Referring to FIGS. 4-5, the first heat dissipating member 20 is secured to the first support plate 17. When the heat dissipating device works, air flows from the input opening 19, through the first ventilation opening 175, via the first heat dissipating member 20, to the output opening 14, and water condensed from the atmosphere drops from the first heat dissipating member 20 to the bottom plate 11 and flows out of the chassis 10 along the bottom plate 11. In an embodiment, the bottom plate 11 is concave, a through hole 112 (shown in FIG. 6) is defined in a bottom of the bottom plate 11, and the water flows out of the chassis 10 via the through hole 112.

In an embodiment, the two side plates 13 are substantially parallel to each other and perpendicular to the bottom plate 11, and the first support plate 17 is substantially perpendicular to the two side plates 13. The first support plate 17 is slanted relative to the bottom plate 11. A support flange 12 is located on each of the two side plates 13 above the bottom plate 11, to support the first heat dissipating member 20. In an embodiment, the support flange on each of the two side plates 13 is substantially perpendicular to each of the two side plates 13 and parallel to the bottom plate 11.

The heat dissipating device further comprises a retaining plate 30. The retaining plate 30 is located on the support flange 12 on each of the two side plates 13, for supporting the first heat dissipating member 20. Each of the support flange 12 defines a plurality of first fixing holes 1211 (shown in FIG. 2), and the retaining plate 30 defines a plurality of second fixing holes 312 at opposite ends. When a plurality of first fasteners, such as screws, are fixed into the plurality of first fixing holes 1211 and the plurality of second fixing holes 312, the retaining plate 30 is secured to the support flanges 12. A space 100 (shown in FIGS. 1 and 6) is defined between the retaining plate 30 and the bottom plate 11. The retaining plate 30 defines a plurality of drain holes 315. When water drops to the retaining plate 30, the accumulated water flows from the retaining plate 30 to the bottom plate 11 via the plurality of drain holes 315.

Two installing pieces 33 extend from opposite ends of the retaining plate 30. Each of the two installing pieces 33 comprises a piece body 34 slantingly extending from the retaining plate 30 and a mounting portion 35 substantially perpendicularly extending from the piece body 34. The mounting portion 35 of each of the two installing pieces 33 defines two first mounting holes 351, and each of the two side plates 13 defines two second mounting holes 133. When two second fasteners, such as screws, are fixed into the two first mounting holes 351 of each of the two installing pieces 33 and the two second mounting holes 133 of each of the two side plates 13, each of the two installing pieces 33 is thereby secured to each of the two side plates 13.

The heat dissipating device further comprises a separated plate 50. The separated plate 50 is slanted relative to the retaining plate 30. Two locking flanges 52 extend in opposite directions from a bottom edge and a top edge of the separated plate 50. Each of the two locking flanges 52 define a plurality of first installing holes 521, and the retaining plate 30 defines a plurality of second installing holes 311. When a plurality of third fasteners, such as screws, is inserted into the plurality of first installing holes 521 of one of the two locking flanges 52 at the bottom edge and the plurality of second installing holes 311, the separated plate 50 is thereby secured to the retaining plate 30.

Two mounting pieces 21 are located on the first heat dissipating member 20 at opposite sides. Each of the two mounting pieces 21 defines two first fastening holes 211, and each of the two side plates 13 defines two second fastening holes 131. When two fourth fasteners 23, such as screws, are fastened into the two second fastening holes 131 of each of the two mounting pieces 21 and the two second fastening holes 131 of each of the two side plates 13, the first heat dissipating member 20 is thereby secured to the two side plates 13.

The chassis 10 further comprises a second support plate 18. The second support plate 18 is substantially parallel to the first support plate 17 and extends to the bottom plate 11. The second support plate 18 and the bottom plate 11 secure a second heat dissipating member 40, which is same as the first dissipating member 20. In an embodiment, the first heat dissipating member 20 and the second heat dissipating member 40 are heat exchangers. The separated plate 50 is located between the first support plate 17 and the second support plate 18. A handgrip 16 is secured to the two side plates 13, to conveniently move the chassis 10, and the handgrip 16 is located between the first support plate 17 and the second support plate 18.

Referring to FIGS. 4-6, when the heat dissipating device works, air also flows from the input opening 19, and through the space 100 and a second ventilation opening 183 of the second support plate 18, via the second heat dissipating member 40, to the output opening 14.
